Best cut flower variety with vase life longer than 5 to 7 days

I have been on the search for varieties of garden roses with a vase life of 7 days or longer with any amount of scent (preferably stronger). However, I find the more fragrant the shorter the vase life. I enjoy having them as cut flower inside and sometimes I sell bouquets for fun. I usually like growing lisianthus because of their vase life but they don't have much scent. I seem to only be able to keep them as cut flowers for 3 to 6 days. Even with the suggest time to harvest them in the morning, and when only 3/4 of the sepals are starting to spread open.

I only tried 3 varieties:

Austin Rose - Lady of Shallott

Floribunda - Koko Loko

Grandiflora - parfuma Madame Anisette ( annoying thorns)

Hybrid Tea - Stilleto

Anyone have tried any varieties that last longer than 7 + days?

Also, I am in zone 4. I have been able to overwinter varieties with a lot of winter protection up to zone 6ish.
